If the War of Northern Aggression has gone on for six more months (possibly less), the entire continental order of the Union would have collapsed as well.
I'm always amused by such self-serving fantasies, because the Civil War was a disaster for the Confederacy. The North from the start had the advantage in population, manufacturing, and allies. As stated by Study.com: While the agricultural, slave-based Southern economy was devastated by the war, the Northern economy benefited from development in many of its industries, including textile and iron production. The war also stimulated the growth of railroads, improving transportation infrastructure.
